F() example in db queries topic guide has an error

Description

​http://docs.djangoproject.com/en/1.3/topics/db/queries/#filters-can-reference-fields-on-the-model

I'm thinking this is incorrect. The F() object references the pingback count, no?

For example, to find a list of all blog entries that have had more comments than
pingbacks, we construct an F() object to reference the comment count, and use
that F() object in the query:

>>> from django.db.models import F
>>> Entry.objects.filter(n_comments__gt=F('n_pingbacks'))
